Abstract

L'invention concerne un procédé et un appareil de mise à jour de noyau (700), et un dispositif informatique (100). Le dispositif informatique (100) exécute le procédé de mise à jour de noyau pour mettre à jour un module de noyau chargeable dans le noyau. Le procédé comprend les étapes suivantes : premièrement, configurer une première table de mappage d'interfaces comme étant invalide (S411), la première table de mappage d'interfaces invalide permettant à un module d'interface d'arrêter d'envoyer une demande de service d'une application de service à une logique de lecteur d'un premier module de logique de lecteur, de sorte que le premier module de logique de lecteur suspende la fourniture d'un service de lecteur à l'application de service ; puis, remplacer le premier module de logique de lecteur dans le module de noyau chargeable avec un deuxième module de logique de lecteur (S412) ; et dans une deuxième table de mappage d'interfaces, enregistrer chaque interface dans le module d'interface et une logique de lecteur dans le deuxième module de logique de lecteur correspondant à l'interface (S413). Après que le module de noyau chargeable a été mis à jour, le deuxième module de logique de lecteur exécute une logique de lecteur sur une nouvelle demande de service réacheminée par le module d'interface selon la deuxième table de mappage d'interfaces et, par conséquent, la fourniture d'un service de lecteur à l'application de service est récupérée.
